How are you planning on accessing it though?

If it's iterated over sequentially then a list works perfectly.

If it's random access then a map works.

What if I want to push/pop it and also access it randomly by index? PHP gets a lot of stick for making arrays serve double purpose but the Elixir advocates of using maps for array purposes are basically arguing for the same thing, no?

Then you are not in functional programming place anymore, and you may want to use an imperative language.

I think it is John Hughes that said "The real question is not 'when should i use functional programming?' but 'when should i use imperative programming?' And the answer is 'When you need random access and complete control of your memory'"

Looks like you want a finger tree.
